Re: Camel Tracer

[Ercan Canlıer <er...@gmail.com>]

Thanks Claus for the answer. I tried to configure the tracer but no luck.
I asked also a question on StackOverflow and here is the details.
On the other hand, what is the preferred way to audit? To write your own
interceptor or logging mechanism?
Apache Camel does not have any audit mechanism with the latest version?
There is also BacklogTracer but i am confused with the components.
If none of them works, i will write my own interceptor or try to send each
message to wire i guess.

After all, my current situation is like below:
I am using the latest version of *Apache Camel 2.22.0*.
The tracer is deprecated at the moment. However, according to the
documentation, we can use it.
In order to store messages, i am using camel-jpa and facing with the
following exception. I have already set camel tracing for the context to
true but didn't work.

*Code:*

    @Override
    public void configure() {
        camelContext.setTracing(true);
        from(CamelComponent.QUARTZ2 + COLON + DOUBLE_SLASH + timerName
+ QUESTION_MARK + "cron=" + cronExpression)
                .transacted()
                .to(CamelComponent.SQL + COLON + sqlFile)
                .bean(mapper, "map")
                .bean(xStreamWriter, "toXml")
                .to(buildFileUrl());
    }<br/>

What might be the possible cause? It somehow does not work with the
transactions.
Thanks in advance,
Best regards,
Ercan
